Be it known tl'IELt -W GLEUGEN TiiR'eKand EMIL Bosnenox, both'citizensof the German Republic, residing at Langerfeld, near Bar men, Germany,and Barmen, Germany, re-

spectively, have inventedcertain new and.

useful Improvements in a Lace-l3raiding Machine, of which the followingisa specif I the mand rel'could not' bedrawn away at all from'gthe.inb'raid ed needles and there would fication. v I

' In the manufacture of a single-thread lace fabric there havebeenhitherto' generally employed, for forming eyesin the midst of theweb, for widening various parts of'the web and so on, so-calledauxiliary threads" which, when the fabric 7 is produced, are

braided into the web and are later removed fromthe latter at completion.To introduce these auxiliary threads a certain'number of {the bobbinsprovided on the machine must be employed, so that, in order-to produce avery d'iiiicultand especially time-absorbing to remove the'threads fromthe completed web, and forthis work many "factory-hands are required.,Finally, these auxiliary threads lead to great wastage of threadmaterial since they cannot be further utilized..

' The object of the presentinvention is to dispense with these auxiliarythreads in the finanufacture of lace :fabric on single-thread braidingmachines andconsequently to obvia'tef the above-described drawbacks vThis c f attained by employingiinsteadof auxil- R iary threads, braidingWires which atone of their ends extend into the thread-collector and attheir outer ,en ds' caniberaisjed and lowered by means of amechanicaldevice The web is:

.It 1s known in the operation of two-thread I braidingmachines (i; e,,thosegha'ving not a singlebut two threads per plate) to employ" wireneedles for producing eyes in themidst of the fabric. 'In this casehoweverithese 'iieedles consist of a'jcomparatively thick, rigid' piecfeof wire and by the braiding be 50 method indeed is employablef in thecase of two-thread machines wherein' th'e threa,

collector, consists of an open 'memberyand wherein af ci own likelbeater Qengaging the fabric' f r'om' above is employed, andwherein comeincorporated with I the fabric, "This Application filed Noveinbe-r 20',1920. sriaiiini. 425,551. 7

A s seen fromFig l, the outfit of the thread lacegbraiding.lmacliine isthe usu l, one, the braiding track being constituted of round p'lates aarran'gejd in a; circleg A ci V v v 3 shows 'the drawing off deviceofthe' cording to the invention there :ismouiited on those of the platesq, whereonan' eye be it formeda mechanical device such as'lwill'beunderstood particularly from Fig.1? of the drawing. This deviceismountedwith its foot 6 centrally" on the particular plate a and f Y i with itsother foot '0" outside the track. Be-

-i tween the twoijupper, mutually lacing ends of the two portions of thedevice is provided; a the passageforthose threads of'the bobbins whichpass through the device, slidable across this passageis the sleeve'e"which serves as holder for theb'raidingLwire' d,

made, :for example, fine steel wire. The.

arrangement is such thatsaid sleeve can be dispo'sedat onemoment on theupper portion of the device and at another moment on'the lower portionthereof, and in that way the wire 01 will at one time be abo'veand atan- I other below the thread of the bobbin running in theouterportion ofthe track. The .sleeve. e holding the wire d is safely retainediby meansof a springf which snaps into this sleeve, while the latter can bereleased from 1 the upper portion o fithe device bymeans of the lever 9so that the sleeveslips down by gravity-on to the lower part of thedevice.

The sleeve 6 may be returned tothe upper part of the device bymean'soffa rod Jalo- I cated inside the device pi'issingthrough thewheel-column of the particular plate. The rod 72, as well as the lever greeeive the r necessary movement from the pattern. gear.

The other or free end the fine, elastic wire (l is conducted through thecollectorring 2', passing between this and themandrella andprojectingsomewhat out of said ring 2'. The elasticity of thewires so acts thatthey do not turn sharply round the loweredgegof the ring i'butleachpasses throu h a lar e bend into its vertical )OSltion In. this way anytight-squeezing oi? the thread-loopsaroundthe wires at this place isavoided I I I r Usually the wires (Z, are in theupper position indicatedin Fig. 2 by. the full; line.

anda wire would be lowered into the; position shown dotted only when athread-loop isto be formed, and would. immediately this'is that thewires (Z become. positioned entirely outside the fabric as will be seen,is raised by the pattern gear the sleeve will be raised .and 'willbehelduponthe depending'inner end of the post 0, by the spring H Inoperation the sleeves are moved upward by the rods h, the upper endsthereof beingshapeditoreceive-the sleeves e, and the posts or hollow.vertical I-shaped standards irom,Fig. In this way any working-in,

oft-he wires "and consequently sticking of the tubular web onthQrHlzU'lCllGl are avoided,

and consequently, the web can be drawn freely 'over the wires.
